Seattle, Washington, December 31, 2012 – Parametric Portfolio Associates LLC (Parametric), a subsidiary of Eaton Vance Corp. (NYSE: EV), and The Clifton Group Investment Management Company (Clifton) announced today the completion of the previously announced purchase of Clifton by Parametric.

Based in Minneapolis, Clifton specializes in providing futures- and options-based overlay services and custom risk management solutions to institutional investors.  Clifton’s overlay services enable clients to add, remove or hedge market exposures in a transparent and efficient manner without disrupting underlying holdings.  Clifton’s risk management strategies employ futures, options and similar instruments to help clients enhance risk-adjusted returns.  As of October 31, 2012, Clifton managed $33.5 billion of funded and overlay assets on behalf of clients.  The Clifton acquisition adds a number of complementary capabilities and product offerings to Parametric, and strengthens Parametric’s position as a market-leading provider of portfolio solutions.
